Abstract (en)
[origin: EP1217210A2] It is an object of the present invention to provide a fluid suction and discharge device capable of continuously discharging fluid with a predetermined flow rate and pressure continuously sucking the fluid without substantially giving rise to pulsation. <??>The invention comprises an inner tube (1) rotatably fitted in a fitting hole of the device body, a cylinder (5) slidably fitted into the inner tube (1), and a plurality of through-holes formed in the inner tube (1), wherein when the cylinder (5) is reciprocated in association with rotation of the inner tube (1), and when one of the through-holes of the inner tube (1) is communicated with a suction hole of the device body, the other through-hole of the inner tube is communicated with a discharge hole of the device body, and when fluid is sucked from a communication suction hole thus communicated, fluid is discharged from the discharge hole thus communicated. <IMAGE>
